Abstract: Provided is an apparatus and method for encoding/decoding moving pictures based on adaptive scanning. The moving picture apparatus and method can increase a compression rate based on adoptive scanning by performing intra prediction onto blocks of a predetermined size, and scanning coefficients acquired from Discrete Cosine Transform (DCT) of a residue signal and quantization differently according to the intra prediction mode. The moving picture encoding apparatus includes: a mode selector for selecting and outputting a prediction mode; a predictor for predicting pixel values of pixels to be encoded of an input video based on the prediction mode to thereby output a residue signal block; a transform/quantization unit for performing DCT onto the residue signal block and quantizing the transformed residue signal block; and an encoder for adaptively scanning and encoding the quantized residue signal block based on the prediction mode.

Abstract: Disclosed are a method and a system that adaptively transform visual contents inputted from a network, in accordance with the visual characteristics of a terminal user. A visual characteristics descriptor that describes the information of the user visual characteristics in a predetermined format is proposed. The descriptor includes the information of the color vision deficiency type and the color vision deficiency degree. The color vision deficiency may be described in numerical degree or textual degree. The invention adaptively transforms visual contents differently in accordance with the color vision deficiency type.

Abstract: The present invention relates to a language representation method and data structure for updating an IPMP tool, a method for updating an IPMP tool using the same and a client apparatus using the same in protection and management of multimedia contents, by which the IPMP tool can be represented dynamically in order to provide convenience to users. In the language representation method for updating an IPMP tool in an MPEG-21 multimedia framework, an update element, which describes update information of the IPMP tool, is defined as a higher level element; and a location element, which has information on a location allowing the IPMP tool to be carried thereto, is described as a lower level element of the update element.
